msdk: adjust the stride align

Browse source 
GstAllocationParams::align is set to 31 in msdkdec/msdken/msdkvpp, hence
the stride align should be greater than or equal to 31, otherwise it
will result in issue
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/861
(msdk: "GStreamer-CRITICAL: gst_buffer_resize_range failed" SPAM),

In addition, the stride should match the pitch alignment in the media driver,
otherwise it will result in some issues when a buffer is shared between
different elements, e.g. the NV12 issue mentioned in commit 3f2314a, which
can be reproduced by `gst-launch-1.0 vidoetestsrc ! msdkvpp !
video/x-raw\(memory:DMABuf\),format=NV12 ! glimagesink`
